Escrow refunds for failed AI API calls — Austin Griffith and Ethereum Foundation endorse it.
465 passing tests from 5,000+ production executions—guards that don't get tired.
Policy enforcement layer stops AI agents from deleting files or leaking credentials—no prompt retraining needed.
Fail-closed execution guard with signed proofs—but risk scoring lacks published methodology or benchmarks.
The idea of inserting a deterministic 'gate' between proposed tool calls and execution is smart and practical: precomputed classification plus an agent-unreachable vault means destructive operations become reversible by default. The README calls out clear mechanics (envelope checks, vault backup, tiered responses and structured denials) which suggests this is more than a thought experiment — it's a focused infra piece for teams that actually let agents touch production.
Minimal sudo wrapper for agents; solves real agent safety, but competes with framework guardrails.
